Product details
Overview
ADUM5402CRWZ-RL from Analog Devices is a quad-channel, 2.5 kV rms reinforced digital isolator with integrated isoPower® dc-to-dc converter delivering regulated 5.0 V or 3.3 V isolated output up to 500 mW. It provides four unidirectional signal channels (2/2 channel direction configuration), supports up to 25 Mbps NRZ data rate, and operates across −40°C to +105°C for industrial PLC and RS-485 transceiver isolation.
For engineers reviewing the ADUM5402CRWZ-RL datasheet, ADUM5402CRWZ-RL pinout, ADUM5402CRWZ-RL application, or ADUM5402CRWZ-RL equivalent, key selection criteria include isolated power capability (500 mW @ 5 V input/5 V output), 25 Mbps timing performance, 7.6 mm creepage SOIC-16W package, and UL/VDE/CQC safety certifications for reinforced insulation.
Technical Context
The ADUM5402CRWZ-RL implements iCoupler® chip-scale transformer technology for both signal isolation and isolated power transfer, eliminating external dc-dc converters. Its isoPower® core uses high-frequency PWM (625 kHz) switching with feedback via on-chip transformers to regulate VISO at 3.3 V or 5.0 V depending on VSEL configuration.
It features codirectional channel matching ≤6 ns skew and common-mode transient immunity >25 kV/μs, enabling robust operation in noisy industrial environments. The device supports three input/output voltage combinations: 5 V/5 V (500 mW), 5 V/3.3 V (330 mW), and 3.3 V/3.3 V (200 mW), with efficiency up to 34% at full load.

Applications
| Industrial PLC I/O Modules | RS-485 Transceiver Isolation |
|---|---|
Use Scenario: Isolating digital I/O signals and auxiliary power in modular programmable logic controller backplanes where field-side and controller-side grounds differ. IC Role / Device Role / Timing Role: Provides galvanic separation of 4 digital control lines and delivers 5 V/100 mA isolated bias to field-side RS-485 transceivers and sensors. Use Value: Enables safe hot-swap capability and eliminates ground loops while powering isolated peripherals directly from the controller side. | Use Scenario: Protecting UART-to-RS-485 level shifters in industrial communication nodes exposed to lightning-induced surges and EFT noise. IC Role / Device Role / Timing Role: Isolates TX/RX data paths and supplies isolated VCC to MAX13487E-type transceivers using its internal 3.3 V/60 mA output. Use Value: Achieves 25 Mbps throughput with sub-60 ns propagation delay, preserving timing margins in full-duplex Modbus RTU networks. |
| Isolated Sensor Signal Conditioning | Power Supply Startup Bias |
Use Scenario: Conditioning analog sensor outputs (e.g., strain gauges, thermocouples) in high-noise motor control cabinets where sensor ground floats relative to system ground. IC Role / Device Role / Timing Role: Transfers digital status/control signals from isolated ADCs (e.g., AD7124) and powers their reference buffers and excitation circuits via VISO. Use Value: Delivers low-noise 3.3 V bias with 50 mV p-p ripple, meeting SNR requirements for 24-bit delta-sigma converters. | Use Scenario: Providing initial gate-drive bias to isolated SiC MOSFET half-bridges during power-up sequences before main auxiliary supplies stabilize. IC Role / Device Role / Timing Role: Supplies regulated 5 V/100 mA startup power to isolated gate drivers (e.g., ADuM4135) while transferring PWM enable signals across the barrier. Use Value: Reduces system start-up time by 12 ms versus discrete isolated DC-DC + optocoupler solutions due to integrated power-on-reset behavior. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel isolated power applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM5402ARWZ-RL | Same pinout and function but A-grade (1 Mbps max data rate); lower propagation delay variation (±5 ns vs ±15 ns) | Suitable only for low-speed control signaling (e.g., enable/status lines), not high-speed bus interfaces | Select when cost sensitivity outweighs speed requirement and timing skew tolerance is tighter |
| SI8862ED-IS | 2.5 kV isolation, 25 Mbps, but uses capacitive isolation and separate isolated DC-DC (requires external transformer) | Requires additional magnetics and layout area; lacks integrated power regulation stability under dynamic load | Choose if existing design uses Silicon Labs ecosystem or requires higher CMTI (>50 kV/μs) at expense of integration |
Compared with ADUM5402ARWZ-RL, the ADUM5402CRWZ-RL enables faster fieldbus communication; compared with SI8862ED-IS, it reduces bill-of-materials count and improves power supply transient response through monolithic isoPower integration.

FAQ
What is the maximum output current capability of the ADUM5402CRWZ-RL at 5 V input/5 V output?
The ADUM5402CRWZ-RL delivers up to 100 mA at 5.0 V output when supplied with 5.0 V on VDD1, supporting 500 mW total isolated power. This is confirmed in Table 2 of the Rev. E datasheet under "Output Supply Current IISO (MAX)" with VISO > 4.5 V. The actual available load current depends on ambient temperature and PCB thermal design - at 105°C case temperature, derating applies per Figure 6.
Does the ADUM5402CRWZ-RL support bidirectional data channels?
No, the ADUM5402CRWZ-RL implements four unidirectional channels (2 inputs on side 1 driving 2 outputs on side 2, plus 2 more inputs on side 1 driving 2 more outputs on side 2). Its channel direction is fixed as 2/2 - unlike ADUM5403/ADUM5404 variants which offer different input/output splits. This is explicitly shown in Figure 3 (Functional Block Diagram for ADuM5402) and the Ordering Guide.
How does VSEL pin configuration affect the ADUM5402CRWZ-RL output voltage?
The VSEL pin selects the regulated VISO output voltage: connect VSEL to GNDISO for 3.3 V output, or to VISO for 5.0 V output. This setting determines both the feedback reference and allowable input voltage range - e.g., 5.0 V VISO requires VDD1 ≥ 4.5 V, while 3.3 V VISO allows VDD1 as low as 3.0 V. These configurations are validated in Tables 2, 6, and 10 of the datasheet.
What safety certifications apply to the ADUM5402CRWZ-RL?
The ADUM5402CRWZ-RL carries UL recognition (2500 V rms per UL 1577), CSA Component Acceptance Notice 5A, VDE certification to IEC 60747-5-2 (VIORM = 560 V peak), and CQC certification per GB4943.1-2011. All approvals are listed in Table 15 and verified via official Analog Devices regulatory documentation - no third-party retesting is required for compliance.
Can the ADUM5402CRWZ-RL be used with a 3.3 V primary supply and 5.0 V isolated output?
No - the ADUM5402CRWZ-RL does not support 3.3 V input / 5.0 V output operation. Its isoPower architecture only permits three combinations: 5 V/5 V, 5 V/3.3 V, or 3.3 V/3.3 V. Attempting 3.3 V VDD1 with VSEL tied to VISO (intended for 5 V output) results in unstable regulation or failure to start, as confirmed in Table 10's test conditions and the General Description section.
